This item is from my parents' house, purchased through a department store mail order 9 years ago. It was used for 2-3 years and then stored. While there is some wear on the bottom of the pot, it is in quite good condition. I will include the 10-year warranty, but please note that it has only 1 year remaining. Thank you for your understanding.
